We’ve known for a while that MPs and NPs are endocrine disruptors. They’re small enough to circulate throughout the body and have now been detected in reproductive organs, semen, and even follicular fluid. These plastics can bind to hormone receptors or release chemicals that interfere with estrogen, testosterone, and progesterone signaling. The consequences? Oxidative stress, […]

We often think of fertility as purely hormonal, rooted in the ovaries, driven by cycles, and governed by age. However, emerging research is painting a more complex picture. A 2025 review article by Fatima Ahmad and colleagues in the Journal of Translational Medicine draws our attention to a critical yet underappreciated player in reproductive health:

A Groundbreaking Study on Myostatin and FSH Let’s talk about a new study from Science that caught my eye—not just because it’s elegant science, but because it changes how we think about fertility hormones. The research by Ongaro et al. (2025) uncovers something surprising: that your muscles may be helping regulate your fertility. Specifically, the

The health of the endometrium—the lining of the uterus—is crucial for successful conception and pregnancy. Recent research has shed light on two conditions that can disrupt this delicate environment: chronic endometritis (CE) and endometrial dysbiosis (ED). While these conditions are often discussed concerning assisted reproductive technologies like IVF, they also have significant implications for natural

Oxytocin, often dubbed the “love hormone,” is renowned for its roles in social bonding, childbirth, and lactation. However, groundbreaking research published in Science Advances by Jessica L. Minder and colleagues has unveiled a novel function of oxytocin: inducing embryonic diapause.​ Understanding Embryonic Diapause Embryonic diapause is a fascinating reproductive strategy observed in over 130 mammalian

The quality of a woman’s eggs—her oocytes—is one of the biggest determinants of fertility. As women age, their oocytes accumulate DNA damage, leading to lower fertility rates and higher chances of chromosomal abnormalities in embryos. A new study published in Nature Communications by Fei Sun and colleagues explores a potential mechanism behind this phenomenon: the

I’ve been reflecting a lot on how our menstrual cycles can offer clues about our fertility, especially after reading The Correlation between Menstrual Characteristics and Fertility in Women of Reproductive Age: A Systematic Review and Meta-Analysis by Cao, Zhao, Dou, Gong, Wang, and Xia. Today, I want to dive deeper into the specific implications of

The Surprising Link Between Stress and Sperm Motility When we think about stress and fertility, it’s usually in a negative light. We often hear that stress can interfere with hormone balance, reduce libido, and even impact ovulation. For men, stress is commonly associated with a decline in sperm quality. However, a fascinating new study published
